In addition, the method includes generating an annotated textual description according to a set of predefined rules that corrects any known errors that were detected in the textual description and generating a process flow diagram from the annotated textual description using a graph generation module. Further, the method includes transmitting the process flow diagram to the originating user using the network.

I. FIELD OF THE INVENTION

The present invention relates generally to a method and system to generate process flow diagrams.

II. BACKGROUND

Business transactions typically include several steps or activities. The activities may be broken down into a series of textual description and visualized using a process flow diagram. For example, a business transaction between a bank customer and a bank teller may consist of several activities or steps when making a deposit. Each activity can be visualized with an association link to another activity.

In the past, flow diagram tools have been used to help visualize a process and the activities. Diagrams are useful in identifying errors and omissions in the process and to detect inefficiencies and redundancies. However, properly developing process flow diagrams from textual descriptions and to identify problems within the process can be tedious and time consuming.

Computer programs may be used to simplify the complexity of developing process diagrams from textual descriptions. A recent approach is premised on the process being modeled as one or more linked steps or activities that collectively describe the process. The process is typically within the context of an organizational structure defining functional roles and relationships. A flow direction defines the interaction of the activities. During this flow, documents, information, or tasks are passed from one person to another for action. The computer software allows a user to represent flows as a connected series of activities or steps. Interconnection between the activities represents the exchange of information. However, a shortcoming of identifying errors in the visual process flow diagram is that the error and omissions may be overlooked. In addition, it is time consuming to generate a process flow diagram from a textual description of a complex process that may include several conditional factors.

Accordingly, there is a need in the art for an improved method and system to generate process flow diagrams that is easy to visualize and use. There is a further need for identifying logical errors and omissions within the textual description of a process before developing the process flow diagram.

VI. DETAILED DESCRIPTION

The word “exemplary” is used herein to mean “serving as an example, instance, or illustration.” Any embodiment or design described herein as “exemplary” is not necessarily to be construed as preferred or advantageous over other embodiments or designs.

The method and system to generate process flow diagrams includes a primary processing portion that is used to identify sentences within a paragraph, perform database search and retrieval of annotations, and diagram construction from annotations. Another portion of the method and system to generate process flow diagrams includes a secondary processing portion that is used for on-going database maintenance that may be performed manually by process experts or automatically. Modules of the method and system may include a sentence identifier module, language parser module, an annotation search and retrieval module, a graph generator module, a graph visualizer module, a database maintenance module, or any combination thereof.

The input to the method and system is a textual process flow description, represented as a paragraph of text. Each sentence in the paragraph is a likely candidate for being a “flow step” in a process. Each sentence is processed individually, and the processing results for each sentence are combined to produce the final output.

There are sophisticated methods for identifying sentences within a paragraph that currently exist. However, in the preferred embodiment the method and system uses a simplified method of locating the punctuation such as periods, question marks, and exclamation points, for example, that appear in the paragraph to decide where one sentence ends, and the next begins. In addition, alternative methods may be used to identify sentence boundaries that are currently under development.

The method and system to generate process flow diagrams includes searching a database to retrieve “expert annotations” for each sentence in the process flow description. If the database does not contain annotations for every sentence in the process flow description, or a syntactically similar sentence, then the method and system records which sentences are missing their corresponding annotations. A process expert may manually add these missing annotations to the database as part of an on-going database maintenance operation or the database may be updated and maintained automatically. The process expert is a person with expert knowledge in the art of writing process flow descriptions and generating process flow diagrams.

In a particular illustrative example of the method and system to generate a process flow diagram, the textual description of a process may be as follows:

-   -   A bank customer gives a transaction to the bank teller. The bank         teller processes the transaction and records it in the bank         system. The bank teller gives a transaction receipt to the bank         customer.

As illustrated in FIG. 2, the first column 120 contains the first sentence of the textual description. The second column 122 contains the domain specific language (“DSL”) annotation for the first sentence. The adjacent third column 124 indicates whether there were any errors, and the fourth column 126 shows the diagram visualization of the first sentence. The second and third sentences are each processed in a similar fashion as illustrated in FIG. 2.

The database search is optimized using a set of predefined rules to find “syntactically similar” sentences in the database. This feature allows the same “expert annotations” to be applied to the processing of other sentences that are similar to the specific sentences that were annotated by a process expert. An “expert annotation” is diagram DSL that correlates to a particular flow step (or sentence). To illustrate how this search method works, “parse trees” are used to facilitate the identification of syntactically similar sentences.

Parse tree diagrams for each sentence in the above example are shown in FIGS. 3-5. The diagrams illustrate how the sentences (S) are constructed from noun phrases (NP), verb phrases (VP), prepositional phrases (PP), and other parts of speech.

In this example, sentence 1 (FIG. 3) and sentence 3 (FIG. 5) are syntactically similar to each other, since both sentences contain the same arrangement of noun phrases, verb phrases, and prepositional phrases. Sentence 2 (FIG. 4) is not syntactically similar to either sentence 1 or 3.

The parse trees shown in FIGS. 3-5 may be produced by an English language parser, such as the Link Grammar Parser, for example, by Davy Temperley, Daniel Sleator, and John Lafferty from Carnegie Mellon University. The Link Grammar Parser assigns a syntactic structure to a given sentence which consists of a set of labeled links connecting pairs of words. The parser also produces a “constituent” representation of a sentence to show noun phrases, verb phrases, etc.

Referring now to FIG. 6, the individual annotations which are retrieved from the database are combined to produce the complete process flow diagram. The diagram construction process is performed in two steps; graph generation, and graph visualization.

The graph generator module uses the expert annotations as input, and creates a “graph representation” of the entire process flow paragraph as shown in FIG. 6. The generated “graph” is a data structure within the system and method that represents the arrangement of the flow diagram elements, which are the steps in the process flow, and the arrows that connect the boxes. The flow diagram elements generated by the system are the “actors”, the “activities”, and the “objects”, which are collectively used by the system to generate the “arrows” and “boxes” on a process flow diagram.

The processing includes collecting the expert annotations from the database for each sentence in the paragraph as the graph is generated from the process flow description. Sentences for which an annotation is not found in the database, is not included in the generated graph. The annotation for each sentence is attempted to be connected to the annotation for the following sentence to create a complete beginning-to-end process flow graph. Any errors that may result when two adjacent sentences could not be connected in the graph are identified. After the graph is generated, it is transformed into a textual description that is used as the input to the graph visualizer module.

Referring now to FIG. 7, the graph visualizer module may use a publicly available graph layout and drawing software, such as Graphviz, for example, which is an open source graph visualization software. Graph visualization is a way of representing structural information as diagrams of abstract graphs and networks. The Graphviz software takes descriptions of graphs in a simple text language, and makes diagrams in useful formats, such as images and scalable vector graphics (SVG) for web pages, PDF or postscript for inclusion in other documents; or display in an interactive graph browser. In the example, a bank customer 130 actor is shown in the first column. The second column is a bank teller 132 actor and the third column is a bank system 134 actor. The first step in the process is that the bank customer 130 gives a transaction to the bank teller 132. The action of giving the transaction to the bank teller 132 is represented by text “Gives Transaction” within a rounded rectangle shape. The information of the transaction is represented by the text “Transaction” within a rectangle shape and placed in the bank teller 132 actor. An association link between the “Gives Transaction” and “Transaction” is represented by a line connecting the two shapes and an arrow representing the flow of the process. Continuing on, the next step is that the bank teller 132 processes the transaction. This action is represented by the text “Processes Transaction” within a rounded rectangle shape. The next action in the process is that the bank teller 132 records the transaction and is represented by the text “Records Transaction” within a rounded rectangle shape. At this point in the process, the “Transaction” is placed within the bank system 134 actor and additionally the bank teller 132 takes another step and “Gives Transaction Receipt” to the bank customer 130. An association link is shown between the “Records Transaction” activity and the “Transaction” within the bank system 134 actor indicating that the “Transaction” is moved to the bank system 134. In addition, an association link is shown between the “Records Transaction” activity and the “Gives Transaction Receipt” activity indicating the direction of the process flow. The final activity in the process is the bank teller 132 gives the transaction receipt to the bank customer 130. This is shown by a rounded rectangle shape with the text “Gives Transaction Receipt” within the bank teller 132 actor. A rectangle shape with the text “Transaction Receipt” is in the bank customer 130 actor indicating that the bank customer 130 is provided with the transaction receipt. An association link points from the activity of “Gives Transaction Receipt” to the “Transaction Receipt” rectangle shape indicating the direction of the process.

Referring now to FIG. 8, the database stores the annotations that are manually produced by a process expert or that are automatically produced when analyzing a sentence from a process description. The annotations may be either a description of a flow diagram, such as a process flow diagram, which corresponds to the sentence, an identification of an error in the phrasing of the sentence, or a suggested revision to the sentence, or any combination thereof. The description of a flow diagram, and the suggested revision, are represented in a domain specific language (“DSL”), which may be input into the database by the process experts or completed automatically. As illustrated in FIG. 8, a first column 140 includes the sentences of a textual description of a process. The second column 142 includes the DSL to generate a diagram visualization for each sentence that does not contain errors. The third column 144 indicates whether there is an error in the respective sentence, and the fourth column 146 is the DSL of the suggested revision to the sentence when an existing annotation is not located in the database, or the sentence contains an error.

The method and system domain specific language is constructed in a manner that allows the process expert to easily indicate which phrases in the specified sentence should be used to create a process flow diagram, and/or a suggested revision to the sentence. The DSL for the sentence is constructed from the sentence by removing the existing punctuation, and adding DSL specific punctuation, as described below.

For example, the DSL may specify the use of square-brackets “[ ]” to delimit the phrases that represent the “actors” in the process flow description. An actor is any of the following that performs an activity: a department or organization, a functional role, a job title, etc. The DSL may specify the use of curly-braces “{ }” to delimit phrases that represent the “objects” and the “activities” in the process flow description. An object is any of the following, which are passed from one actor to another actor: an object, entity, or data. An activity is a function or action that is performed by an actor.

In a particular illustrative example of the method and system to generate a process flow diagram, the textual description of a process may be as follows:

-   -   A bank customer gives a transaction to the bank teller. If the         bank teller identifies an error with the transaction, then he         returns it to the bank customer. Otherwise, the bank teller         processes the transaction and records it in the bank system. The         bank teller gives a transaction receipt to the bank customer.

In sentences that describe a flow step that is a conditional statement (IF-THEN statement), the DSL specifies the use of keywords, such as IF, THEN, ELSE, THENIF, and ELSEIF, as shown in FIG. 9. For example, the first sentence 148 in the table identifies a conditional statement to take the action to return the transaction to the customer if there is an error with the transaction. Next, the sentence is converted to DSL 150 for the graph visualizer module to generate a portion of the diagram 152 for the first sentence 148. The second sentence 154 is converted next to DSL 156 that is used to generate a second portion of the diagram 158 for the second sentence 154.

Referring now to FIG. 10, the final diagram of the process is illustrated and indicates the direction of flow through the process. This includes the conditional statement of identifying an error and the direction of flow through the process. In summary, the method and system that generates the final diagram includes reading the originating textual description of a process, dividing the description into individual flow steps (or activities, sentences, etc.), and transmitting each step to a database. In addition, the method and system includes providing a DSL annotation from the database or indicating that a new DSL annotation is required because an exiting DSL annotation for a particular step has not been yet created. If a new DSL annotation is required, the annotation may be generated automatically using an algorithm or may be manually generated by a process expert and the new annotation is saved and updated in the database.

The algorithm automatically generates an annotation for a new sentences if the new sentence is “syntactically similar” to one or more sentences already in the database. This feature allows the same “expert annotations” to be applied to the processing of other sentences that are similar to the specific sentences that were annotated by a process expert. For each sentence in the database, the system algorithm creates a “parse tree” similar to that shown in FIGS. 3-5, which is used to facilitate the identification of syntactically similar sentences. The parse tree shows how the sentences (S) are constructed from noun phrases (NP), verb phrases (VP), prepositional phrases (PP), and other parts of speech. A “DSL Generation Rule” is also included in the database for each sentence. The DSL Generation Rule describes how to generate an annotation from the sentence's parse tree. The system algorithm uses the DSL Generation Rule from a syntactically similar sentence, to automatically generate the DSL annotations for the new sentence. The DSL Generation Rule contains placeholders (such as NP₁) to specify which parts of the new sentence to include in the generated DSL.

The graph visualizer module may use the features in Graphviz to allow the user to specify a horizontal orientation such as left-to-right placement of the diagram shapes, and/or a vertical orientation such as top-to-bottom placement of the diagram shapes. A horizontal orientation is illustrated in FIG. 10 and a vertical orientation is illustrated in FIG. 11. The method and system operates the same in either orientation and is simply user preference.

The method and system to generate process flow diagrams may include a process expert (or multiple experts), or algorithm, reviewing the originating user's natural language descriptions or process flow description. Each process flow step is reviewed individually. For the flow steps that are determined to be valid, the method and system prepares a flow diagram annotation by constructing a textual representation of the diagram using DSL retrieved from the database for a particular step. For the flow steps that are invalid or unable to locate an existing annotation for the flow step, the method and system prepares an annotation and/or a suggested correction for the invalid or new flow step.

In a particular embodiment, the method and system uses a “social network” to control the exchange of information between the originating user and the process experts The phrase “social network” relates to the manner in which the “expert annotations” are accessed in the database. In a social network, a mechanism called a “social graph” is used to describe how the different pieces of information in the database are accessed, and by whom. In the method and system described herein, each “process expert” is a node in the social graph. The process expert may add connections (in the social graph) to other process experts. This creates links between various nodes in the graph, which define “information sharing” rules between process experts.

When an originating user submits a process flow description to the system, the user may specify the process expert, whose annotations they prefer. Since multiple process experts are performing the on-going database maintenance, there exists the possibility that some expert annotations will “be better or more accurate” than others. The social graph allows each process expert to create links only to other process experts, whose annotations they approve. In this way, the originating user is assured that his process flow description will be processed using only the annotations created by his preferred process expert, and the annotations created by an “approved” list of other process experts.

The method and system may divide the description into individual flow steps and send a flow step search request to the database. The database returns a DSL annotation or an unavailable status to the system. If the method and system receives an unavailable status, then the individual flow step is sent to the process expert or to be processed automatically by an algorithm. The process expert (or algorithm) examines each flow step and determines if they are acceptable. If the method and system accepts the flow step then a DSL annotation is created for the flow step, and entered into the database. The method and system processes the annotations and generates process flow diagrams and suggestions. The system stores the annotated flows in a database. Otherwise, the process expert or algorithm enters an error annotation into the system. For example, for flow steps that are invalid, the method and system prepares an error annotation, and optionally a suggested correction for the invalid flow step. For flow steps that cannot be determined to be valid or invalid, no annotations are prepared, and the flow step is omitted from the generated diagram.

Referring now to FIG. 12, a method to generate process flow diagrams is illustrated. The method includes receiving a textual description of a process, at 402. Moving to 404, the method includes accessing a database for diagram DSL that corresponds to each flow step of the process. In addition, the method includes retrieving DSL for flow steps that exist in the database, at 406, and generating new diagram DSL, at 408, for each flow step not found in the database. Continuing to 410, the method also includes updating the database with the new diagram DSL and generating a process flow diagram from the retrieved DSL and any newly generated DSL, at 412.
